I agree with Bill and Gareth. I have sold over 30 Dart 16s in Ireland. We have 10 at my Club and another club has 16. Most of them are raced - maybe not as fanatically as the Spitfires and Formula 18s. We had 9 at our Nationals.
One guy, who is on his 2nd Dart 16, now wants the new version. He could have a Spitfire, but he likes a cat that he can knock around a bit <img src="http://www.catsailor.com/forums/images/graemlins/blush.gif" alt="" /> .
If I bring a cat on holidays, it is always the Dart 16, not the Spitfire. I feel safer in the open sea (where there are no rescue facilities) in a cat where I can easily reef the main and roll the jib, if the wind gets up.
